Best bet up front is to run OEM or OEM-replacements. In back you can turn the drums and run D/W350 shoes, the drums are the same but the shoes on the 250s are narrower. Some guys have trouble with the ABS pump and bypass them. Everything has to be working properly or they don't work the greatest. Some have had a frozen caliper trigger the dash lights.
I find a lot of info on the Diesel Truck Resource Forums. I've put up a link to some info, just go down til you find the post about brakes, there is info on the 3 inch brake shoe swap and even going to a hydroboost system. This is for diesels, but the info on the brakes will interchange for a gasser, the Cummins had a vacuum pump and vacuum assisted brakes until 98.
